TLDR
In this paper, a volume visualization technique for generating a 3D visualization image of an internal organ using volume visualization techniques is presented. But this technique is not suitable for the visualization of complex 3D objects.Abstract:
Methods for generating a three-dimensional visualization image of an object, such as an internal organ, using volume visualization techniques are provided. The techniques include a multi-scan imaging method; a multi-resolution imaging method; and a method for generating a skeleton of a complex three dimension object. The applications include virtual cystoscopy, virtual laryngoscopy, virtual angiography, among others.read more

User interface for remote control of medical devices
TL;DR: In this article, an interface for remotely controlling a medical device in a patient's body provides a two dimensional display of a three dimensional rendering of the operating region, and allows the user to select the orientation or location of the distal end of the medical device on the display and then operate a navigation system to cause the device to approximately assume the selected orientation.

Method and system for patient-specific modeling of blood flow
TL;DR: In this article, a system for determining cardiovascular information for a patient is described, which includes at least one computer system configured to receive patient-specific data regarding a geometry of the patient's heart, and create a three-dimensional model representing at least a portion of the heart based on the patient specific data.

Anatomical visualization and measurement system
TL;DR: In this article, a method for determining the risk of rupture of a blood vessel using an appropriate set of 2-D slice images obtained by scanning the blood vessel was presented, the method consisting of: generating a mesh model of the vessel using the set of two-dimensional slice images; conducting finite element stress analysis on the mesh model to calculate the level of stress on different locations on the meshes; and determining the risks of rupture based on the calculated levels of stress at different locations of the mesh models.

System and method for using three dimensional infrared imaging to provide detailed anatomical structure maps
TL;DR: In this article, skeletonized feature maps define subpixel intersections that serve as anatomical landmarks to aggregate multiple images for models of larger regions of the body, and to transform images into precise standard poses.

System and method for performing a three-dimensional virtual segmentation and examination
TL;DR: In this article, a system and method for generating a three-dimensional visualization image of an object such as an organ using volume visualization techniques and exploring the image using a guided navigation system which allows the operator to travel along a flight path and to adjust the view to a particular portion of the image of interest in order to identify polyps, cysts or other abnormal features in the visualized organ.
